Gremlin — In-Depth Analysis
Gremlin is the pet tied to the Pet Mutation Machine: its passive, Machine Mischief, increases your odds of rolling rarer mutations from the Pet Mutation Machine. The wiki gives no percentage for that boost, so how large it is remains unwritten.
The only listed source is the Trick-or-Treating Rewards, where the Gremlin has a 5% chance, one in twenty. The same table gives the Pumpkin Ghoul only 1%. Trick-or-Treating costs 10 Candy Corn to start, there is an 80% chance of a treat, a trick refunds 25% of the cost, and the price doubles after each attempt (10, 20, 40, 80 and so on) before resetting every 8 hours.
The Gremlin is a Mythical pet with 60,000 hunger, added on October 24, 2026, in the second part of the Halloween Event 2026. The wiki puts it under Spooky Type Pets, shows one image, and still marks the Appearance section "To be added", so how it looks is not described.
